PPLIUATION FILED ulm?, 1907.

wir anco `Q A To all lwhom it may concern:

Be it known that I, HENRY M. HALLETT, of Ludington, in the county of Mason and State of Michigan, have invented certain new 5 and useful Improvements in Smoking-Pipes and I do hereby declare the following to be a full, clear, and exact description of the inthe art to which it appertains to make and 10 use the same.

The object of this invention is to provide an attachment for tobacco pi es for effecting the drying or evaporation o nicotin, saliva, and other moistures which usually accumulate in pipe bowls; and also to allow the smoke to pass freely from the pipe bowl without coming i nto contact with saliva and other f moistures so disagreeable to smokers. The invention will be hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional view of a pipe embody- I ing my improvement. Fig. 2 is a view of lthe attachment removed. Fig. 3 is a face view of the tobacco rest. Fig. 4 is a view of the lower portion of the attachment. Fig. 5 is a cross sectional view on line 5 5, Fig. 1. Referring to the drawings, the attachment -comprises a plate 1 constituting the rest or support for the tobacco load, and a cup 2 secured to and depending from the underside of such plate, both being located in the bottom of the bowl, a circumferential space, however, being left between the cu and the r surrounding wall of the bowl. T ese two parts are united by a nutted screw 3, the L ead of which rests on the to of plate 1, 'while the nut 4 bears against t e bottom of .the cup. This screw is surrounded by an asbestos sleeve 5. In plate 1 I form a series of openings 6 by striking up the metal from the underside thereof, such openings ermitting the smoke to pass freely, while t e projecting walls prevent ashes, nicotin, and other objectionable substances from reachthe bottom of the bowl. This plate becomesr` very much heated, when in use, and

Y. ydrying or .evaporation of the nicotin or oils ,r of tobacco. The cup is also formed with a series of smoke-outlet openings 7 formed by e the metal being struck up from the interior ofthe cup, the walls rojecting outwardly i Y A.55 and do Nnwardly `so t at -saliva or. otl,;ier if y moistui-es are prevented from enterin Specification of Letters Patent.

befouling the cup chamber. The heat of burning tobacco is transmitted through th nutted screw 3 to the underside 'ofthel c u and such heat is intended to dry or evaporate any saliva which may reach' the bowl throngV the stem. The asbestos sleeve 5 servesltjo prevent the heat conducted by the screw-'j being given off before it reaches theunde face of cup 2. y

In practice, the outer edge f of plat slightly turned upward when f the p device.- pressed tightly into the pipe thereb preventing ashes, nicotln, or particlesfof tobacco from passing between the device and the inside of the bowl.l As statedfbefor such substances are likewise prevented-fro Y passing through the protectedv openings-in the top plate 1, although free passage'ls'ali means of m im-fi i Q.

pipe stem into the bowlv isfqulckl'y dried orf lowed for the smoke. B provement all moisture' owingfthrou evaporated.

A device of the character described i`sex tremely simple and inexpensive, and may-'be readily Replaced,4 at but slight cost,

conditions require. i

I claim as my invention:

1. The combination with a pipe, ofan attachment designed to fit in the'bowl thereof,

comprising a plate forming a rest or support.

for the tobacco load having a series of smoke i i outlets, a cup depending fromsaid platef. through which the smoke must pass in its'.r

outward travel, a screw uniting said cu to said plate and designed to transmit the eat of the latter to the underside of said cup, and, a non-heat conductor surrounding said screw 'e within said cutpj Y 1 2. The com inationwith a pipe, of an attachment designed to fit in the bowl thereof,

comprising a plate having a series of Y'smoke outlet o enings, means extending upwardly from suc plate surrounding said openings to prevent ashes, nicotin; etc. from passing therethrough, a cup depending from the underside of said plate, with a circumferential space between it and the pipe bowl, said cu also having smoke outlet openings, an

means protecting such openings for preventing saliva from entering said cup. l 3. The combination with a pipe, of an attachment designed to fit-in the bowl thereof, comorisinga metallic plate having a series of smokev outlet openings formed by striking up no metal, the edges of the latter around said openings preventing ashes, nicotin, etc.

yfrom assing therethrough, a metallic cup from the undersidethereof, a cup depending from said plate havinga series or, smoke outlet openings formed by being struck up from the underside thereof, la circumferential space bei Wall of the owl, a'screw connecting said cup to said plate, the heat of the latter being designed to be'transmitted through said screw to the underside of the cup, and an asbestos sleeve surrounding said screw Within the cup.

In testimony whereof, I have signed thls specification in the presence of two subscribing Witnesses.
